Wrist watches are commonly powered using one or rarely two button/coin cell batteries, and these batteries have a limited operating lifetime. When replacing an old battery with the new one, the best practice is to use batteries recommended by the watch manufacturers.
However, finding the exact type and model can be sometimes confusing due to the different labels some battery brands are using for their batteries. Also, using silver-oxide instead of alkaline batteries can prolong the watch operating time on a single battery.

Complementary Metal Oxide Semiconductor (CMOS) battery is a small, mostly button/coin cell battery that provides power to the small memory that stores information about the BIOS settings.
When the CMOS battery dies, BIOS resets its setting, including date, hard drive settings, boot order, etc., and in many situations, OS can't load properly.
When something like that happens, the only course of action is to replace the CMOS battery.

The car battery provides energy not only for cranking the engine, but it also powers a broad range of devices that may be turned on when the engine is off, even when the car is locked, like GPS units, alarms, and other security systems, multimedia devices, lights, etc.
While car batteries feature a nominal voltage of 12 volts, in real life, this voltage can be anywhere from just a few volts (or even 0 volts!) to almost or even slightly over 15 volts. The exact battery voltage depends on the engine being turned On or Off and the battery's charge condition, age, load, temperature, etc.

Marine, automotive and industrial batteries are designed to operate in tough conditions due to vibrations and other mechanical stress. They must be able to power various electric and electronic devices and when the main engine must be started, they must be able to provide large currents in order to start large, often multiple gasoline or even diesel engines even when not fully charged. Such requirements significantly reduce the number of potential 1000 CCA marine, automotive, and industrial battery models.
CCA (Cold Cranking Amps), CA (Cranking Amps) or MCA (Marine Cranking Amps), and HCA (Hot Cranking Amps) define the maximum current that a battery is able to provide under certain conditions.

Electric golf cart battery packs are based on 6V, 8V, and 12V lead-acid batteries, although in recent times, 12V, 24V, 36V, and 48V golf cart lithium batteries are also being manufactured. So, how many batteries are in a 48-volt golf cart?

Golf carts and other electric vehicles rely on their built-in batteries to provide them with enough power and energy for propulsion.
In order to increase the range and acceleration of the golf cart, the golf cart battery must be able to both store and to be able to release plenty of energy, often rapidly, while not causing weight penalties. Also, the golf cart battery must be able to cycle a lot, tolerate deep cycle discharges, to accept the charge quickly and similar. These requirements are not easy ones...

Conversions between electrical units are usually simple and straightforward - take a formula, write down values, and let the calculator do the rest.
However, in real life, things are not always that simple, especially when converting units that require at least one unit to be known. If You wish to know more about converting watts to amps, amps to watts, volt-amps to watts, and similar, read carefully...

Conversion between Cold Cranking Amps (CCA) and Amp Hours (Ah) is not a direct one, for one very simple reason: Cold Cranking Amps describe the ability of the battery to provide strong currents required for starting/cranking of internal combustion engines, usually for 30 seconds, while Amp Hours (Ah) describes the capacity of the battery and its ability to provide certain current for, usually, 20 hours.
Basically, Cold Cranking Amps (CCA) and Amp Hours (Ah) both describe the capacity of the battery and its ability to provide current for some time - they are just two extremes of the battery usage.

Deep cycle batteries may be recharged in many ways, but the best thing to do is to follow recommendations by their manufacturers regarding charging voltages, temperatures, and currents.
However, in real-life situations, such ideal charging conditions are not always possible.

Dual fuel power generators are types of generators that can out-of-box use both gasoline or propane, which can be very helpful in emergencies where gasoline can be hard to find.
Also, propane as fuel has many advantages over gasoline - it is more environment friendly, it stocks up more easily, it is more engine-friendly fuel, etc.

Wet/flooded, gel-cell, AGM, and lithium 12V 100Ah deep cycle batteries are a very popular group of deep cycle and dual-purpose batteries, offering relatively large capacities (100+ Ah), a large amount of stored energy (1200+ Wh), and large discharge currents at acceptable price and weight.
Due to the maintenance requirements, wet/flooded batteries are used rarely, with the SLA Gel and AGM batteries being most common. Also, lithium 12V 100Ah batteries are getting more and more present on the market, offering huge weight savings.

Trolling motors are commonly used as means of propulsion on kayaks of various sizes, especially on fishing kayaks, intended for longer fishing trips that last for hours and sometimes even for days.
The main issue any kayak owner has is the kayak's load capacity. While electric trolling motors are lightweight and feature excellent weight to thrust ratio, their batteries are anything but light - unless lithium kayak trolling batteries are used.

Fish finder batteries for kayaks and smaller boats must be lightweight and compact, but accept charge quickly from various sources, and should be able to power the fish finder during the entire fishing session without the need to be recharged before going to shore or starting the main engine (if present).
Fish finder batteries are spill-proof AGM and Gel-Cell lead-acid batteries and Lithium Iron Phosphate (LiFePO4) batteries. Most fish finder batteries feature nominal capacity in the 5 - 20 Ah range.

Power inverters for cars and trucks are becoming increasingly popular due to the large number of devices and gadgets that must be powered or at least occasionally charged while in the car.
As such, car power inverters should feature a car cigarette lighter adapter plug (12V DC) providing high-speed charging for smartphones, tablets, cameras, drones, but also for laptops and similar devices. However, due to the power limitations of the car cigarette lighter adapter, the output power of car inverters is also limited.

Space heaters convert electric energy directly into heat, making them rather inefficient, but simple and affordable units, commonly used for warming up tents, RV, and similar objects when being off-the-grid, but also for quick warming up of rooms and other areas at homes and apartments.
Since they entirely rely on electric energy, many people wonder how much electricity does a space heater use and how they can power such devices while being outdoors.

While HP is a unit of power, kWh is a unit of energy and direct conversion of these two units is not possible, without introducing the third parameter - time (T[s]).
kWh to HP and HP to kWh conversions are very important when both power and energy of internal combustion engines are transferred, stored, and compared with the energy and power of electric motors, inverters, pumps, winches, and other similar units that are powered by electric energy.

SI prefixes are very important in electrical engineering but also in everyday life. Their use is relatively easy, but it can also cause many problems when done incorrectly.
Watts to kilowatts, kilowatts to megawatts, and other conversions are very important when electric energy and power of electric motors, pumps, winches, inverters, batteries, and other devices are being calculated, planned, transferred, or being used. SI prefixes help significantly, especially when dealing with very large or very small values.
